Description

The HQProp Ethix S4 propeller is engineered for pilots seeking a high-performance prop for 5-inch FPV builds. The 5×3.65 tri-blade configuration generates substantial thrust for rapid acceleration and tight cornering, making it ideal for both technical racing tracks and dynamic freestyle maneuvers. The polycarbonate construction provides excellent durability against minor impacts and flex, ensuring consistent performance across multiple flight sessions.

Designed with a 12.8mm hub and a 6mm hub thickness, the S4 offers a secure and rigid mounting interface to minimize power loss and vibration. The distinct Lemon Lime color provides both high visibility in flight and a personalized aesthetic for your drone build. This propeller is optimized for use with 2207-2306 size brushless motors commonly found on 5-inch quads, operating efficiently on 4S to 6S LiPo battery systems.

Key Features

High-Thrust Tri-Blade Design: Three-blade configuration maximizes thrust density and responsive control for aggressive flying.
Durable Polycarbonate Build: Offers high impact resistance and consistent flex characteristics for reliable performance.
Optimized Aerodynamic Profile: Blade shape is tuned for efficient power delivery and reduced high-speed flutter.
Precision Balanced Hubs: 12.8mm hub diameter with reinforced structure for minimal vibration and secure motor attachment.
Wide Voltage Compatibility: Engineered to perform efficiently across the common 4S to 6S LiPo voltage range for FPV drones.
High-Visibility Color: Lemon Lime finish enhances orientation tracking during high-speed flight.

Applications

5-inch FPV Racing Drones: For competitive racing quads requiring maximum acceleration and cornering grip.
5-inch Freestyle FPV Drones: Ideal for dynamic tricks and maneuvers where predictable thrust and durability are key.
High-Performance 5-inch Cinematic Drones: Suitable for aggressive flying and carrying action camera payloads like GoPro.
DIY 5-inch Quadcopter Builds: A reliable choice for custom builds using 2207-2306 size motors on 4S-6S power.

Frequently Asked Questions

What size motors are these HQProp Ethix S4 5-inch props designed for?

The Ethix S4 5x3.65 props are optimized for standard 5-inch FPV drone motors, typically in the 2207 to 2306 stator size range. They feature a standard 5mm bore and are compatible with most motor shafts for this class. Ensure your motor's KV rating and battery voltage (4S-6S) match the high-thrust demands of this propeller for optimal performance.

Are these propellers balanced out of the package?

HQProp propellers are known for their good manufacturing consistency, but for peak performance, especially in high-RPM FPV applications, we recommend a final dynamic balance check before use. Minor balancing may be required to eliminate high-frequency vibrations, which can improve video feed quality and flight controller stability.

Can I use these on a 6S-powered 5-inch drone?

Yes, the polycarbonate construction of the Ethix S4 propellers is durable enough for 6S power systems. However, the high 3.65-inch pitch generates significant load. Ensure your 2207-2306 motors and ESCs are rated to handle the increased current draw at 6S voltages to prevent overheating or desync issues during aggressive throttle punches.
